Remote Cameras Confirm Wildlife In Chernobyl Exclusion Zone

Everyone knows what happened at Chernobyl. Just mentioning the name of the Ukrainian nuclear power plant is enough for people to envision the accident and the damage that its meltdown brought. Not surprisingly, humans aren’t allowed to venture into the area surrounding the site, the Chernobyl Exclusion Zone (CEZ). The restricted CEZ encompasses the bordering lands of Ukraine and Belarus impacted by radiation fallout from the accident, which occurred April 26, 1986. But there are no restrictions on the movements of wild animals nearby. Back in 2015, a study relied on the presence of track marks to estimate the animals living in the area.

Flood Warning Systems

Chapter Overview: Flood Warning A Real-Time Solution Streamflow Measurements Typical Flood Warning System Monitoring Location Data Management Quality Assurance Recommended Equipment Why Monitoring Matters While some areas are more prone to flooding than others, the establishment of flood warning systems near any major waterway or body of water provides critical information that can protect property and save lives. Of course, the most effective flood warning methods extend beyond the installation of gages and telemetry equipment, and employ qualified staff and carefully designed procedures to provide the earliest warning about whether a flood should be expected, when it will occur, and how severe it will be.

Hydropeaking Hurts Aquatic Insects, A Favorite Fish Food

An investigation on the Colorado River led by scientists at the U.S. Geological Survey has found that some of fishes’ favorite foods -- aquatic insects -- may be greatly damaged by the practice of hydropeaking, or the momentary pulses of water released by dams in creating hydropower. The research, informed primarily by data points gathered by citizen scientists, underscores the essential roles that insects play in the food webs of rivers. Findings of the work point to the possibility of reduced biodiversity downstream, something that water managers may be able to mitigate by using alternative hydropower practices. Hydropeaking is a practice typically used when electricity demands go up, usually during daytime.

Ashumet Pond Nitrogen Questions

A lot of attention has been given to the role of runoff in spurring harmful algal blooms. But what about the actions taking place beneath the surface via groundwater? It’s not always easy to capture data in this zone, but scientists at the U.S. Geological Survey have given it a shot. In a recent investigation at Massachusetts’ Ashumet Pond , they led a group of researchers, including others from the Virginia Institute of Marine Science, looking at the interactions taking place between groundwater around the small Cape Cod lake and the water it holds. In part, their results show that additions or reductions in nitrogen through groundwater movement can be a bit hard to predict.
